Installing required libraries on Ubuntu

TRIQS 3.2 has been tested on the Ubuntu LTS version 22.04. Earlier versions are not supported.

Install the following packages which are necessary to build TRIQS and use it:

sudo apt-get install cmake g++-12 gfortran git hdf5-tools \
     libopenblas-dev libboost-dev libfftw3-dev libgfortran5 \
     libgmp-dev libhdf5-dev libopenmpi-dev \
     python3-dev python3-mako python3-matplotlib \
     python3-mpi4py python3-numpy python3-scipy

We need to further specify the compiler to be used for the TRIQS compilation using:

export CXX=g++-12

If you wish to use the jupyter notebook with triqs you can install it using:

sudo apt-get install jupyter-notebook

For full functionality of the C++2Py Tool, please install clang and the libclang library:

sudo apt-get install clang libclang-dev python3-clang


If you encounter compile-time error messages such as:

fatal error: mpi.h: No such file or directory
fatal error: H5public.h: No such file or directory

make sure that the include directories of your openmpi and hdf5 installation are in the CPLUS_INCLUDE_PATH environment variable:

export CPLUS_INCLUDE_PATH=/usr/include/$(gcc -dumpmachine)/openmpi/:/usr/include/hdf5/serial/:$CPLUS_INCLUDE_PATH
